If you love offense, you loved West Virginia vs. Baylor. And you loved it more if you were a fan of Geno Smith and the Mountaineers.

Smith added to a growing Heisman Trophy resume by completing 45-of-51 passes for 656 yards and a Big 12 record-tying eight touchdowns—with five of those going to Stedman Bailey, who also had 303 receiving yards—and the Mountaineers won a scoring fest 70-63 in Morgantown. It was the highest-scoring game in Big 12 history.

"We did what it took to win today," Smith told a TV reporter afterward. "… They put the pressure on us to keep scoring."

West Virginia rolled up a school-record 807 yards of offense, and Baylor 700 in the Mountaineers’ Big 12 debut against a conference opponent. Among those 1,507 yards, 37 first downs were gained, and six receivers had at least 100 yards receiving.

Smith outdueled Baylor's Nick Florence, who broke Heisman Trophy-winning predecessor Robert Griffin III's school record with 581 yards. Florence threw for five TDs.

"We expect to score that many points a game," Florence said. "But the goal is to score more than our opponent and we came up a little short today."

But the biggest star was Smith, whose eight touchdown passes tied a Big 12 record. And it only took one game for him to break it.

"Can you please tell me how you can improve on that?" West Virginia coach Dana Holgorsen said of his quarterback's play.
